ROLLER FOR ENDLESS BELTS.

SPECIFICATION forming part of Letters Patent No. 280,282, dated June 26,1883. i

Application filed April 21,1883. (No model.) i i T all whom it mayconcern:

Be it known that I, REUBEN i. S. BACON, a citizen of the United States,residing at Springfield, in the county of Clarke and State of Ohio, haveinvented certain new and useful Improvements in Rollers for EndlessBelts, and I do declare the following to bea full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters'and figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in rollers for endless belts.

My invention relates to that class of rollers which are made of wood andused in harvestover the tenons c a.

ers, thrashing-machines, and all kinds of machines in which canvas beltsare used for conveyers 1or elevators. A

In the rollers now in use, more especially those in harvesters, used forconveying and elevating the grain to the binder, the rollers are oftensplit in pieces by the strain upon the journals from the shrinkage ofthe canvas and from other causes, and the object of my invention is toobviate the danger of thus having the rollers destroyed, by constructingthe ends and the journals so as to prevent all tendency to splitting ofthe wood.

' Figurevl is a view of my improved roller with the ends shown detached.Fig. 2 is an inside view of the cap end seen on the left end. Fig. 3 isan end view of the body part as seen from the left. Fig. 4 is aview ofthe opposite end of the same. Fig. 5 is an inside View of the cap seenat the right.. in Fig. l. Fig. 6 is a longitudinal elevation of thejournal seen on the right in Fig. l.

A, Fig. l, represents a wooden roller, such as is used to carry anendless canvas belt in a harvester having a binder attachment. It haslong tenons c .and a at either end, which each have cross-slots c and ccut in them, at right angles with each other, across the center of thetenon. They extend about two inches into the wooden piece, to allow theweb flanges or feathers c and c2 in the bottom of the caps B and C toenter them as the latter are driven on The caps B and C are to describeit.

both made of malleable iron, and are cast entire with end pieces and theweb-flanges c and c2 within them. The cap C is cast` integral `with itsjournal bL thereon; but the cap B is cast with a square hole, c, in itscenter, the an,- gles of which are in line with the inner flanges, c, asseen in Fig. 5. The wooden shaft of the roller has also a correspondinghole, b, cut centrally therein, to admit the square portion of the`journal-iron b, which is driven through the hole e in cap B and intothe hole b after the cap has been driven over the tenoncto its place. Ashoulder or collar, d, on the journal-iron prevents any danger of itsbeing driven in too far.

VIn all machinery where wooden rollers are used they aremore or lessliable to split from torsion, and in the construction of my improvedroller with the cap ends having the crossflanges to secure them on theinside, and a pin driven through each of the caps diametrically acrosstheir axial line after they are driven upon the roller-shafts to furthersecure them, it becomes almost impossible to tear the roller asunder, nomatter what the strain or shearing stress upon it may be. Holes in thecaps and i in thetenons c and c, for the purpose of fastening the capson, can be made to register. An iron pin for this purpose can be used.

By reference to the cap B in Fig. 1 it will be seen through the openingbroken out that the hole e is strengthened by the flanges c, extendinginward a sufficient distance to support the sides of the square sleeve,within which the hole e is located.

As there is no difference between the operation of this roller and thosein ordinaryuse, the motion being continuous rotary obtained from thedrivingfbelt, itlwill not be necessary In case repairs are needed or anewlshaft is required, the caps can b'e rel moved by driving out the pini, which is dressed off smooth at either end when inserted.

I claim as my invention- 1. Aroller for endless belts, having tenonswith a cross-cleft therein to adapt it to engage with cross-flanges inthe interior of a metal cap provided with aj ournal-bearing extendingtherefrom, substantially as set forth.

2. A cap for a roller for endless belts, ofmalleable iron, cast integralwith itsl journal, and

IOO

having eross-iianges extending inward from the 'bottom of the same, saidiianges being adapted to enter a cross-cleft in the end of the roll erwhen the cap is driven over the tenon of the same, as set forth.

3. In a roller for endless belts, a eap driven over a tenon on the endof the sanie, having an interior sleeve central therewith, fiangesoonneeting the angles of said sleeve with its inner walls to strengthenthe same, and having a square hole through said sleeve to adapt it toreceive the square shaft of a journal-iron eX- tending through said capinto the body of the roller, substantially as set forth.

4. A roller for endless belts, having a crossoleft in the tenon end ofthe same, and a square hole in its center to adapt it for the engagementof a cap having a square inner sleeve, and crossiianges connecting saidsleeve with its interior walls, substantially as set forth.

5. The Combination, with the roller having a tenon end provided with across-cleft and a square hole eentraltherewith, of a cap having acentral sleeve with flanges connecting it with the interior Walls, asquare hole therein, and a journal-iron having asquare shaft adapted tobe inserted through said cap into the body of the roller, as set forth.

6. In a roller for endless belts, having Caps of malleable iron drivenover the tenon endsl REUBEN S. BACON.
